Yes, there is; it’s pretty easy. The list manager should know how to do it, or can find it in the list owner’s manual.

The best way to deal with this is to force new subscribers to be moderated until they make a meaningful post. That’s just a matter of setting the list defaults to “no post”, then removing that restriction after a new user posts appropriately. This would also solve the problem if the recalcitrant poster changes email addresses.

Recently a rogue poster has started posting weird irrelevant stuff (Spanish obscenities, as far as I can tell) – but he subscribes, posts a few, then unsubs. I don’t think he changes email addresses. I’m wondering if there’s a way to block someone from subscribing at all?
